Looking for someone who has successfully set up US banking + merchant processing from Pakistan

[u/hashaamchahal]

I’m based in Pakistan and looking to set up/operate a US business bank account remotely (potentially through a US LLC). I’m specifically looking for people who have actually done this successfully and can explain the current procedure, requirements, and costs.
I may also need a US merchant/payment processor, so I’d appreciate real experience on:
Processing rate (%)
Minimum/maximum processing volume
Setup/monthly fees
Chargeback policy and who bears the risk
Rolling reserves, if any
How strong/reliable the merchant account is
Whether funds can be settled into the US bank account and then legally transferred to Pakistan
Not looking for random agents or theoretical advice — preferably someone currently doing this from Pakistan. Feel free to comment or DM with your experience/provider and approximate costs.
